Okay my own memory leakage has been caught and hung in the public square.
Mine was not a patch, but rather code one of my fellow coders hand coded.
That being code to allow color codes in say, goss, titles etc
Seems he was mallocing a buffer EVERY time it was called and nevered
bothered to free it anyplace, or just assumed it would be freed on its own.
I just gave his routine a global buffer of MAX_STRING_LENGTH just like
buf, buf2, etal to use.
Now as to how this relates to anyones elses memory leakage troubles.
To find this leak, i searched for all occurences of malloc.
I added a mudlog call directly after each one, spitting out file name,
line number, bytes allocated
I then went to my shell and repetetively did an:
ps -aux | grep circle
This shows the memory usage under BSDi
Well i noted that the memory went up by 8 bytes all the time, save when
people login etc, but the CONSTANT increase appeared to be in 8 byte
increments.
So i went to my syslog, and looked for my debug messages, with allocation
size of 8 bytes. only one place did that, and wouldnt you know it, that
was my troubles.
Had it not been QUITE so easy, i would have then also added debug
messages to all free() calls and looked for anything glaring, like
unmatched malloc/free pairs
If you have a leak, youd have to at least HOPE there's only one, and its
size is going to be someone conformed
I did try lint as the one kind gentelmen suggested, but my lack of
knowledge on its usage, even after studying man pages, kept it from being
of much use to me.
Anyways, I suggest a similar tactic to those having similar troubles.
To those who had contrcutive advice on ways to track it down, 1 million
thanks.
To those who decided my questions, was a good reason to flaunt themselves
as the only REAL coder alive, and me just a stupid peon that deserves any
troubles i might ever have .... well ill just concentrate on the REAL
people who only post when they have something helpful to say.
